Specification of Letters Patent.

Patented Dec. 16,1919.

Application filed July 17, 1916, Serial No. 109,831. Renewed April 11,1919. Serial No. 289,409.

following is a full, clear, and exact specification.

This invention relates to a class of ap- "paratus for providing animatedpictures of objects.

My invention has for its object primarily to provide an apparatuswhereby moving pictures of living objects, scenery and the like maybeprinted and produced on an opaque strip, such as paper, or otherflexible,

X material of a character ordinarily classed as being noncombust1b1e,.1n order to permit various pictures for educational,amusement and other purposes to be produced for eX- hibition in placesof instruction and pleasure as well as in homes without endangering theauditors to fire as is incident to the use of the usual very inflammabletransparent films, though in instances moving pictures may be printedand produced on transparent films by the use of this process. This isaccomplished mainly by providing a process consisting of exposing asensitized photo,-

graphic .strip to an. opaque photographic negative strip synchronouslywith operative rays of light being reflected on the negative whereby thepictures on the negative will be produced on the sensitized strip toproduce a positive, or by exposing a sensitized photo- 1 graphic stripto a positive at the same time.

reflecting rays of light on the positive whereby the pictures of thepositive will be recorded thereon to produce a negative, thensubsequently exposing a sensitized photographic strip to thephotographic negative:

simultaneously with operative rays of light being reflected on thenegative so that the pictures on the negative will be produced on thesensitized stri to produce a positive.

A practical em odiment is represented in i the accompanying drawingforming a part of this specification in which similar charthe descrition. 1

In the rawings, Figure 1 19a side eleva tion of one form of apparatusembodying my invention.

Fig. 2 is a fragmentary view showing partly in detail a side view of theparts of the apparatus illustrated in Fig. 1.

. Fig. 3 is a sectional View, partly in detail, taken through theapparatus, and

Fig. 4 is a section, partly in detail, taken through one of thereflectors used in the apparatus. a l

The apparatus may be constructed of an outer casing 10 and a removableinner casing 11, both of which may be of any desired size as well asbeing made of any suitable material: The outer casing v10 is preferablysubstantially rectangular in shape to provide side walls 12 and 13, abottom 14;, a

front wall 15, a rear wall, not shown, and a' top 16 which is hinged, at17, to one of the side walls for opening and closing the upper end ofthe outer casing, this casing being made so that'light will be preventedfrom entering thereinto.

lhe inner casing 11 is also preferably substantially rectangular inshape, and this .cas-' ing is .of a height so as to fit closely betweenthe diottom 14 and the top 16 of the outer casing, while the width andlength of theinner casing, is smaller than the outer casing, as shown,to provide'spaces'between the sides and fronts of both of the casings.The inner casing is constructed with side walls 18 and 19, a bottom 20,a front wall 21, and a rear wall, not shown, while the top,-

as 22, is hinged, at 23, to one of the side walls to permit the upperend of the casing 29, and through this partition adjacent to its sidewalls are openings 30' and 31. Entrance is gained into the lowermagazine of the inner casing by a door 32 hinged, at 33, to the sidewall 18 of the inner casing as well as by a second door 34 which ishinged, at

35, to the side wall 19 of the casing. Through the central part of theside wall 18 of the inner casing is an opening 36 the passage throughwhich is adapted to be side wall 18 between its opening 36 and thetransverse partition 28 are two spaced openings 44 and 45, while throughthe lower art of the side wall 19 between its opening 39 and thetransverse partition 28- are also two spaced openings 46 and 47 each ofwhich is in register with each of the openings 44 and 45.

J ournaled in the front and rear walls of the. inner casing 11 aretwos'pa-ced shafts 48 and 49 extending through the magazin 25 of thecasing, and these shafts are of lengths so that one of the correspondingends thereof extend beyondthe front wall 21 of the casing. In the frontand rear walls of the inner casing11, and projecting through themagazine 29 are two otherspaced shafts 50 and 51 also of lengths so thatone of their corresponding ends extend beyond the front wall of thecasing. Re-

movably held on the shaft 48 is a delivery reel 52 having wrappedthereon a film, or strip, as 53, of paper, or other opaque materialwhich is ordinarily considered as being non-combustible, and removablyheld on the shaft 49 is a second delivery reel 54 having wrapped thereona film or strip, as 55, which may also be of transparent material, orthis strip may also be of paper, or other opaque material of a characterusually considered as being non-combustible. The opaque strip 53 may bea photographic negative having any desired number of animated picturesof objects or the strip may be an opaque positive with animated picturesof objects thereon.

The strip 55 may be photographically sensitized for printing positivepictures thereon when the strip 53 is a negative, or the strip 55 may bephotographically sensi tized for producing a negative when the strip 53is a positive, as will be hereinafter more fully explained. On'the shaft50 in the magazine 29 of the inner. casing is re-' movably held a reel56 for receiving the moving picturestrip 53 from the delivery reel 52,and on the shaft 51 is another removable reel 57 for receiving themoving picture strip 55 from the delivery reel 54.

When the strip 53is threaded through the interior of the machine fromthe delivery reel 52 to the receiving reel 56 it guidedpast the opening36 of the side wall 18 of the inner casing 1'1, and. when the 18interiorly of the inner casing is a framing device, as 58, and on theside wall 19 also on the interior of the casing is another framingdevice 59. The framing devices 58 and 59 are of similar'formations, andthese devices may be of any well known, or preferred types, for example,forms of the devices illustrated, each of which is composed of a frontplate 60 with right angularly extending arms 61 and 62 on its upper andlower ends, these arms of one of the front plates projecting from theinner surface of the side wall 18 of the inner casing to space the frontplate from this wall before the opening 36, while the arms of the secondfront plate extend from the inner surface of the side wall 19 of theinner casing so. as to space the front plate from the side wall 19 infront of its opening 39. Through the upper part of the front plate 60 ofeach of the framing devices is an opening 63, and this opening of onefront plate is in register with the. opening 36 of the side wall 18 ofthe inner casing, while the opening 63 of the other front plate is inregister with the opening 39 of the side wall 19 of the inner casing.Through the lower part of the front plate 60 of each of the framingdevices is an opening 64,

and this opening of one front plate is in register with'the opening 45of the side wall bolts, or screws, as 66 and 67, passed through openingsin the front plate to allow the second plate to be adjusted toward andfrom its opposed side wall of. the inner casing, and through each ofthese adj ustablc second plates is a window 68, both'of the windowsbeing in register wlth each other as well as being in register with theopenings 36 and 39 of the side walls of the inner casing and in registerwith the openings 63 of the front plate 60. The moving picture strip 53is movably disposed between the adjustable plate 65- of the framingdevice 58 and the side wall 18 of the inner casing, and the strip 55 islikewise -movably arranged between the adjustable plate 65 of theframing device 59 and theside wall 19' of the inner casing so that byemploying the plates in this manner they are adapted to be adjusted foryieldingly holding the Ill strips 53 and 55 during their movements toexpose successive parts thereof through the windows 68 and through theopenings 63 of the front plates 60 of the frammg devices.

In order to transmit the strips 53 and 55 in unison through the machinefrom the delivery reels 52 and 54 to the receiving reels 56 and 57,respectively, I provide a mechanism, as 69. The mechanism 69 isconstructed of a drive shaft, or stud 70 ournaled in a bearing on thecentral part of the front wall 21 of the inner casing 11 of the machine,and this shaft is of a length to extend beyond thefront wall 15 of theouter casincr 10 through an opening therein. The shaft 70 may be drivenby any suitable power, such as a crank handle 71 provided on the end ofthe shaft exteriorly of the outer casing of the machine. On the shaft 70adjacent to the front wall21 of the inner casing is a' drive gear 72,and also on this shaft between the drive gear and the front wall of theouter casing are four sprocket wheels 73, 74, 75, 76. Extending from thefront plate 21 of the inner casing on aline inent with the shaft "7 O,and in proximity to the side wall 18 of the inner casing, is journaled astud 77 with an idler gear 78 held thereon, and this gear is in meshwith the drive gear 7 2; p Also held on the stud 77 are two spacedsprocket wheels 79 and 80. Projecting from the front plate 21 of theinner casing on alinement with the shaft 70, and contiguous to the sidewall 19 of the inner casing, is journaled a stud 81 with another idlergear 82 held thereon, and this idler gear is in mesh with the drive gear72.

- Over the sprocket wheel 73 of the shaft 70 is guided a sprocket chain83 which passes over a sprocket wheel 84 held on a shaft 85 which isjournaled to the upper partof the side wall 19 interiorly of the innercasing, and on the shaft 85 is a sprocket,'or toothed drum 86 adapted tobe rotated in the opening 43 of the side wall 19 of the inner casing forengaging the usual aper-' tures, not shown, provided in the strip 55.

. Over the sprocket wheel'74 of the shaft 70 is guided a sprocket chain87 which passes over a sprocket wheel 88 held on a shaft 89 jou'rnaledin the lower partof the side wall 19 interiorly of the inner casing, andon this shaft adjacent to the sprocket wheel. 88 is another sprocketwheel 90, while on the central part of the shaft 89 is a sprocket, or

toothed drum 91 adapted to be rotated in the opening 46 for engaging theapertures of the strip 55. .Guided over the sprocketwheel 5 of the shaftis a sprocket chain 92 passing also over -a sprocket wheel 93 held on ashaft 94 journaled on the lower part of the sidewall 18 exteriorly ofthe inner casing, and on the shaft 94 is a sprocket, or toothed drum 95which is aropening 42 of the side wall 18 of the inner ,7

casing so as to also engage the apertures of the strip 53. On thesprocket wheel 80 of the stud 77 is a sprocket chain 100 which is guidedover a sprocket wheel 101 provided on the shaft 48 of the delivery reel52 exteriorly of the front wall of the inner casing of. the machine, andon the sprocket Wheel 79 of the stud 77 is a sprocket chain 102 passingover a sprocket 103 arranged on the shaft 50 of the receiving reelexteriorly of the inner casing. On the front wall 21 of the inner casingofthe machine adjacent to its side wall 19 is journaled'a stud 104having a pinion 105 held thereon, and this pinion is in mesh with thegear 82 on the stud 81. Also on the stud 104 is held a sprocket wheel106 onwhich is a sprocket chain 107 passing over a sprocket wheel 108 onthe shaft 49 of the delivery reel 54 exteriorly of the front wall 21 ofthe inner casing. stud 89 is a sprocket chain 109 which is guided over asprocket wheel 110 provided on the shaft 51 of the receiving reel 57exteriorly Of the inner casing. By properly proportioning the diametersof the drive gear 72, gears, 78, 82, sprocket wheels 73, 74,

, caused to be driven in unison at corresponding speeds forrevolving'the toothed drums 84, 88, 94, 97 to transmit the strips 53 and55 also in unison through the machine.

lVhen the motion picture strip, 53 is threaded through the machine it isguided from the delivery reel 52 through the opening 20 of thetransverse partition 24 of the inner casing 11, and the strip is movedinto engagement .with the toothed drum 99 to which it is held in movablecontact by C0111- pression rollers, as 111, of well known forms arrangedon the side wall 18 interiorly of the inner casing. The strip is thenpassed through an opening 112 in the top wall 113 of a casing, or box,as 114, which extends interiorly of the inner casing of the machinebefore the registered windows 63 and '68 of the framingxlevice 58, theboxbeing formed with a bottom wall 115 having an opening Over thesprocket wheel 90 of the I 116 and afront wall 117 with an opening 118therethrough which is in, register with the windows 63 and 68 of theframing device 58;

A loop, as 119, is formed in the strip 53 at 5 "the opening 112 of thebox 114, and the strip is guided betweenthe side wall 18 of the innercasin lland the adjustableplate 65 of the framing device 58 for beingtransmitted before the windows 63 and 68 of this framing device as wellas before the opening 118 of the front wall 117 of the box 114. From theframing device 58 the strip 53 is passed through the opening 116 of thebottom wall i of the box 114, and after a second loop- 120 is formed inthe strip it is guided into engagement with the sprocket drum 95, thestrip being held in movable contact with this sprocket drum bycompression rollers, as 121, provided on the side wall 18 of the innercas- 20 ing of the machine. The strip is then passed through the opening30'of the transverse partition 28'of the inner casing 21 for beingwrapped on the receiving reel 56 during the transmission of thestripthrough the ma- 25 chine.

When the motion picture strip 55 is threaded' through the machine it isguided fromthe' delivery reel 54 through the opening 27 of thetransverse partition 24 of the inner cas- 30 ing 11, and the strip ismoved into engagement with the toothed drum 86 to which it is held inmovable contact by compression rollers, as 122, of well known typesprovided on the sidewall 19 of the inner casing. A loop,-

as 123, is then formed in the strip 55 after which the strip is arrangedbetween the side wall. 19 of the inner casing and the adjustable plate65 of the framing device 59. A.

second loop, as 124, is then formed in the strip which is guided intoengagement with the sprocket drum 91, and the strip is held in movablecontact with this sproc et drum ranged on-the exterior of the side wall19 of the inner casing. From the sprocket drum ti) through the machine.

In order. to cause the strips 53 and 55 to be intermittently checkedduring the trans mission through the machine, on the exterior of thewall 18 of the inner casing 11 55 of the machine is journaled a shaft126 one endof which extends beyond the front wall 21 of the innercasing, and on this extending end of the shaft is a pinion 127 which isin mesh with the gear 78 of the stud 77. Also on the shaft 126 is a drum128 disposed in the opening 45 of the side wall 18 of the inner casing,and extending from diametrically opposite parts'of this drumare SBtSiOfspaced teeth, as 129 and 130, ,adapted to en- N gage the apertures ofthe moving picture by a pair of compression rollers, as 125, ar-

strip, the strip being held in movable contact with the toothed drum bya block, as 131, which is yieldingly forced inwardly of the opening 64of the front plate 60 of the framing device 58 so as to abut against thestrip to hold it in engagement with the toothed drum by a spring, as132, arranged on the front plate of this framing device. 011the-exterior of the side wall 19 of the inner casing of the machine isjournaled a shaft 133 one end of which extends beyond the front wall 21of the inner casing, and on this end'of t'he shaft is a pinion 134meshing with the pinion 105 of the stud 104. On the shaft 133 anddisposed in the opening 47 of the side wall 19 of the casing is a drum135 jecting from diametrically opposite parts thereof, and which engagethe apertures of the moving picture strip 55, this strip being held inmovable contact with the toothed drum by a block, as 138, yieldinglyforced inwardly of the opening 64 of the front plate 60 of the framingdevice 59 so as to contact with the strip to hold it in engagement withthe toothed drum 135 by means of a spring,

, havingspaced sets of teeth 136 and 137 pro as 139, providedon thefront plate of the,

framing device 59. The pinions 127 and 134 are proportioned so that whenthe other parts of the mechanism 69 are operated, as above mentioned,the shafts 126 and 133 will be driven at speeds corresponding to theother shafts and studs of the mechanism, and the drums 128 and 135 arealso proportioned together with the sets of teeth of each drum beingrelatively spaced apart that the movement of the strips 53 and 54 whentransmitted through the machine will be in-:

termittentlyv checked synchronously so that corresponding successiveportions of both strips will be exposed in unison to each other throughthe 'registered windows and openings 63 and 68 of the framing devices 58and 59 aswell as through the opening 118 of the box 114 interiorly ofthe inner casing.

While specific forms of the intermittent checking devices are shown anddescrlbed,

instead thereof I may employ any other wellknown, or preferred types ofdevices for causing the strips to be intermittently checked the machine.On the front wall 117 0 box 114 interiorly of the inner casing of themachine is a lens barrel 140 with one or more lenses, as141, mountedtherein, and this bar'- during their transmission throngl f t e relisarranged so that the focus of the lens will be in the ath' of thesuccessive parts of the moving picture strips exposed through theregistered windows and open1ngs-63 and '68 of the framing devices 58and59 aswell as through the opening 118 of the box 114.

Interiorly of the lens box 114 of the inner casing arearranged one, oraplurality of lamps, as 142 and 143, which are referably electricallylightedfrom any su ta le source of supply, for example from a battery,as

144, from one terminal of which is a wire 145 leading to one pole of oneof the lamps, and the corresponding second poles of the lamps areconnected by a wire 146. From the second terminal of the battery 144 isa wire 147 leading to a switch 148 adapted to be swung into engagementwith a contact 149 of a wire 150 leading to the other pole of the secondelectric lamp so that by swinging the switch 148 into engagement withthe contact 149 the lamps will be lighted by the circuit being closed,the current passing from the battery overthe wire 145 to one of thelamps, through which the current will pass over the wire 146, and alsofrom the battery the current will pass over the wire 147, through theswitch 148, and over the wire 150 to and through the second electriclamp, the light from these lamps being extinguished by disconnecting theswitch 148 from the contact 149. Each of the lamps 142 and 143 ismounted in a reflector, as 151, which may be parabolic, or pear-shaped,as shown, in the form of a mirror, or the reflector'maybe of metalhaving an interior refleeting surface for deflecting the rays of lightfrom its lamp through the opening, as 152, of the reflector. One of thereflectors is arranged in the upper part of the box 114, while the otherreflector is mounted in the lower part of the box, and these reflectorsare disposed in converging arrangement so that the rays of the lampswill be deflected on the portions of the strip 53 exposed through theregistered windows 63 and 68 of the framing device 58. The exposures ofthe strip 53 to the lens 141 will. thereby be effected by the reflectedrays of light from these lamps.

,To cut-ofl' at intervals the light deflected on the exposures of thestrip 53 when transmitted through the machine, a shutter, as 153, of anydesired form may be provided. The shutter 153 is disposed interiorly ofthe inner casing for being revolved across the plane ofv the focus ofthe lens 141, and this gear 155 in mesh with a bevel'gear 156 on theupper part of a vertically disposed shaft 157 which is ournaled inbearings on the exterior, of the side wall 18 of the inner casing. Onthe lower end of the shaft 157 is another bevel gear 158 meshing with abevel gear 159 provided on the shaft 126 of the toothed drum,orintermittent operating device 128,

= and these bevel gears of the shutter are proportioned so as to beoperated when the shaft 126 is driven for cutting-01f the light on thestrip 53 at proper intervals-as is in- CldGIltWltll customary methodsfor shuttingoff the light in operating the usual moving picturemachines.

In order to print the moving pictures of a photographic opaque negativestrip on a sensitized opaque photographic strip, or ona sensitizedtransparent photographic strip to produce a positive the negative iswrapped on the delivery reel 52, and the sensitized strip is threaded inthe machine, as above explained, for transmission to the receiving reel56 so that successive portions of the negative strip will be exposedthrough the through the windows 63 and 68 of the fram- I ing device 58to the sensitized positive. Simultaneously with the focusingof thepictures of the negative the light from the lamps 142 and 143 isdeflected by the reflectors 151 on the exposures of the negative strip53, and the pictures will thereby be printed on the sensitized strip 54to produce a positive when the machine 15 operated.

To produce a photographic opaque negative, or a photographic transparentnegative of the pictures of an opaque positive strip, the positive striis wrapped on the delivery reel 52, and tile positive is arranged in themachine, as hereinbefore explained, for transmission to the receivingreel- 56 so that successive portions of the positive will be exposedthrough the windows 63 and 68 of the framing device 58 to the lens. Asensitized photographic strip for producing a negative is wrapped on thedeliv reel 54, and the strip 55 is threaded throug the machine, asdescribed, so as to be transmitted to the receiving reel 57. When themachine is operated the successive pictures of the positive exposed tothe lens 141 will by employin thelight of the lamps, as above describebe focused on the sensitized strip, 55 for recording the picturesthereon which are afterward converted to a photographic negative in theusual manner.

To print the pictures of this photographic negative when the strip isopaque on a sensitized opaque strip, or on a transparent photographicsensitized strip, to produce a positive, the negative strip 53 iswrapped on the delivery reel 52, and the strip is threaded'in themachine, as explained, for transmission to the receiving reel 56 so thatconsecutive i portions of the negative will be exposed through thewindows 63 and'68 of the framing devibe 58. The sensitized strip 55 islens 141 on the successive exposures of the,

- sensitized strip to produce a positive of the pictures when the stripis developed in the customary manner. By this process moving picturesmay be readily printed from an opaque negative strip on an opaque; ortransparent sensitized strip to produce positive pictures of thenegatlve, or moving pictures may be reproduced from an opaque positivestrip to an opaque, or transparent sensitized strip to produce anegative and then printed on a sensitized strip to produce a positive.Moreover, by employing a suitable lens the pictures may be enlarged orreduced in sizes, as occasion requires To operate the machine followingthe proper arrangement of the moving picture strip in the-machine, thecrank handle 71 is turned for revolving the shaft 70, and the drive gear72 with the sprocket wheels 7 3, 74, 75, 76 will be revolved. The gears78 and 82 will then be rotated in opposite directions. The rotation ofthe gear 78 will drive the sprocket chains 92, 96, 100, 102 for drivingthe' shafts 94, 98, 126, 48, to rotate the sprocket wheels 93,.97, 101,103 with the pinion 127, drum 128, and toothed drums 95 and 99 tointermittently transmit the strip 53 from the delivery reel 52 to thereceiving reel 56, the shutter 153 being operated in unison with theseparts, as hereinbefore explained. Simultaneously with the rotation ofthe sprocket wheels 73, 74, 75, '76 the sprocket chains 83 and 87 willbe driven to rotate the sprocket wheel 84, shaft 85, toothed drum 86,sprocket wheels 88, 90, shaft 89, toothed drum 91, sprocket chain 109,sprocket wheel 110 and shaft 51 of the receiving reel 57, and with therotation of the gear 82, the pinion 105, sprocket wheel 106, shaft 104,pinion 134, shaft 133, drum 135, sprocket chain 107, sprocket wheel 108,and theshaft 49 will be operated to intermittently transmit the strip 55from the delivery reel, 54 to the receiving reel 57. By previouslyclosing the electric circuitto the lamps 142 and 143, as aboveexplained, the light from the lamps will.be deflected by the reflectorson the strip 53 during the operation of the machine, while a specificfor operating said gearing.
